[O.B.Left]

Don't overthink this, this is very basic. Don't get confused by the words rotated or swinging or hitting, the question was regarding the pressure points location not it's action. For most a strong single action grip is by far the best choice and is mandatory in homers basic motion acquired motion and total motion curriculums. If you go to any tour event one thing that will stand out with nearly all their swings is their trigger finger grip with the first fleshy pad of the right index finger (pressure sensing pad) on the back of the shaft.

You should see the bronze casts done of the grips of memorable winners of the Open that are displayed at the R&A museum in St Andrews. Trigger fingers all.

The pressure point does Rotate though for the Drag Loader . He or she does load the knuckle at the base of the index finger during Drag Loading, Startdown, Longitudinal Acceleration ...assuming thats what attaches to the top of the handle. Then it Rotates to the first joint or pad (if that whats attached to the aft) during Radial Acceleration.

The Drive Loader just employs the first joint or the pad if you want . Ted hits but drag loads instead of drive loads most often so he's loading the knuckle in STartdown then Drives hard with a Right Arm Throw during Radial Acceleration.
